SPECIFICATION forming part of Letters Patent No. 758,226, dated April 26, 1904. Application filed December 24,1903. Serial No. 186,467. on model.)

T0 (tZZ whom) it may concern.-

Be it known that LJAMns Vinson, a citizen of features of construction whereby the desired results are attained, as hereinafter shown and described. and specified in the claims.

In the drawings illustrative of the invention, in which corresponding parts are denoted by like designating characters; Figure 1 is a sectional elevation of the improved apparatus. Fig. 2 is a plan view of a portion of the apparatus. Fig. 3 is an enlarged sectional detail of one of the intake-pipes and its guardplate. Fig. .4: is a side view of the parts shown in Fig. 3.

The improved apparatus comprises an inclosed air-chamber 10 of any suitable size, a vertical air-shaft section 11, and a horizontal air-shaft section 12 between the air-chamber and the vertical section, the horizontal section curving, as at 13, where it unites with the vertical section, so that no abrupt corners or passage-ways exist from the chamber 10 to the discharge or upper end of the vertical section. The chamber 10 is provided with a plurality of inlet-openings 14, covered by laterally-extended guard-plates 15, spaced from the walls of the chamber 10, as by blocks 27, so that the air cannot blow directly through the openings to interfere with the action. The horizontal sectionlQ is flaring where it leaves the chamber 10, as at 16, to converge and confine the air-currents and increase their force as they pass to the shaft-section.

Disposed for rotation in the flue-section, preferably in the horizontal section 12, is a power-wheel constructed of screw-formed radiating-blades 17, mounted upon a shaft 18, which is in turn mounted longitudinally in the flue-section as by bearings 19, the fluesection having a return-bend 20, so that one end of the shaft may project therethrough and be supplied with a-drive-pulley 21, as shown. It will be obvious that by this arrangement the currents of air which constantly flow upwardly through a vertical air-shaft, such as illustrated herein, will be utilized to rapidly rotate the shaft 18 and drive-pulley 21 and by suitable transmitting means may be transmitted to any desired mechanical structure, and thus utilized for any useful purpose for which it is adapted.

A controlling gate or valve 22 is located in the air-shaft between the power-Wheel and the chamber 10 to enable the air-currents to be cut oil independently of the air-chamber, if preferred.

A hood 24 will preferably be rotatively mounted upon the outlet end of the vertical shaft-section 11 to prevent any adverse currents blowing downwardly into the air-shafts and interfering with the action of the power wheel. The hood will preferably be mounted upon ball-bearings 26 and provided with windvanes 25 to insure its proper position relative to the direction of the Wind.

The air-shafts and other parts may be of any size, height, or length; but, generally speaking, the higher the vertical section 11 the greater the force of the air-currents, and con seq uently greater force, imparted to the powerwheel and its transmission mechanism. I do not, therefore, desire to be limited in any manner to the size or length of the air-shafts or to the size or capacity of the air-chamber, but reserve the right to construct the device of any desired size or modify the parts in other particulars and to make such alterations and changes as may fairly fall within the scope ofthe claims.

Having thus described the invention, what I claim is 1. In'a motor, a closed alr-chamber having air-inlets provided with covering-shields spaced from the walls of the chamber, an airshaft leading from said air chamber and formed of a horizontal section and a vertical section, a power-wheel formed of radiating screw-formed blades and mounted for rotation in said air-shaft, and means for transmitting motion from said power-wheel.

2. In a motor, a closed air-chamber having air-inlets, an air-shaft formed of a horizontal section and a vertical section and leading from said air-chamber, a power-Wheel formed of radiating screw-formed blades upon a shaft mounted for rotation in said air-shaft,.pro jecting through the Wall thereof and provided With a drive-pulley exteriorly thereof, said air-shaft having a return-bend opposite said pulley.

'3. In a motor, a closed air-chamber having air inlets provided With covering shields spaced from the walls of the chamber, an airshaft leading from said chamber and formed of a horizontal section and a vertical section, saidhorizontal section having a return-bend, a hood mounted revolubly at the upper end JAMES vINsoN.
